Another important series of lectures is The Philadelphia Doctorate Course. These provide the most comprehensive statement of the spirit in relation to the physical universe, and what the spirit is capable of achieving. These lectures explore and answer fundamentals about existence, including the true nature of reality, the anatomy of universes and their construction, maintenance and destruction.

By applying the spiritual truths contained in these lectures, an individual can undo the agreements which trap him in MEST and thus step outside of the physical universe and begin to operate fully as a spirit, independent of the traps of materiality.

The traps of the MEST universe are also the subject of a series of recorded lectures known as Exteriorization and the Phenomena of Space, which describe how a thetan, under the constant bombardment of the physical universe, becomes unable to emanate energy and so collapses in on himself like a dark star. Thus he becomes the effect of the material universe. These lectures demonstrate how to reverse this process and restore a thetan’s ability to emanate and to create space.
